Terri Lou Dunkelberger was a heroine to her fellow employees. Yet unbeknownst to them, she also likely had been ripping them off. Dunkelberger, an employee of the Sioux Falls bus system and former financial secretary of Amalgamated Transit Union Local 1356, was indicted in U.S. District Court for the District of South Dakota on June 3 for embezzling more than $24,000 in union funds. She pleaded not guilty the following day. Dunkelberger is currently out on bond. If convicted, she faces up to five years in prison.
